for the price vmods are nice, however with a vmod you are stuck using carts or old school atties
whereas reo's you can use any 510 open ended (unsealed) tank/atty
however if you are just wanting a good dripping atty that's not overly complicated vision's eternity is a nice atty...it can hold 25 drops at a time, if you don't want to make coils you can buy premade coils...installing is easy, just put the lead wires into two teeny tiny pins, push pins onto pegs, trim lead wires and you're done....
if you don't want to drip but still want all the flavor of dripping it can be reassembled into tank mode (it's an ego-t type a tank) and the juice will drip from the tank onto the coil
